@Meddler - The New Leash System Punishes Counterjungling
In what I'm certain is an unintended interaction, jungle monsters will now follow you forever. If you eat up a delicious big raptor and take a few small raptors, leaving one left for the enemy jungler to have to clear (denying him XP and gold as is the intention of counterjungling), that one raptor will chase you past red buff. That gives the enemy jungler lots of additional information he didn't have before, namely that you are still in his jungle and he can quickly call his team to come corner you.
Yes, ranged jungling is a thing now. Hooray hooray but this interaction is not good for the game, so maybe we can find a happy compromise between reset if you step more than 5 feet away from the camp and chase you past red buff.
